One-dimensional posterior distributions, and 68% and 95% confidence level marginalised contours for the dark energy parameters (w₀ and w_a) and the parameters h and σ₈. Here we compare results obtained with a multipole cut at ℓ_max = 1500 (green contours) with those related to the analysis with the scales cut k_max = 0.25 h Mpc⁻¹ (red contours). The mock data of Euclid cosmic shear assume Halofit+PKequal non-linear corrections as reference, while the parameter estimation is performed with either HMCode (right panel), or Halofit (left panel). Black dashed lines mark the fiducial model.
